SOLITARY SANDPIPEB. 59 



for believing that it winters in South America, and has not been 

 distinguished there from the eastern form. The following state- 

 ment of the winter range doubtless includes both forms, but it is not 

 safe to conclude that the eastern form goes to eastern South America 

 and the western form to the Pacific coast. It is known that the 

 eastern form migrates to the Pacific coast of Mexico, and it is prob- 

 able that thence southward the two forms commingle both in migra- 

 tion and during the winter. The species as a whole ranges south in 

 winter to Buenos Aires, Argentina (Barrows) ; to Caiza, in south- 

 eastern Bolivia (Salvadori) ; and to Chorillos, central Peru (Tacza- 

 nowski) . It occurs regularly also at this season in northern South 

 America to Guiana (Quelch), Venezuela (Berlepsch and Hartert), 

 and Colombia (Salvin and Godman). North of South America it is 

 not common anywhere in winter, and it may not winter at any of 

 the following places, but it has been noted as late as December in 

 Porto Rico (Bowdish), Costa Rica (Todd), Yucatan (Sharpe), Vera- 

 cruz (Sharpe) , and northern Lower California (Stephens) . 



Migration range. — ^A specimen was taken in Greenland August 1, 

 1878, at Kangek, latitude 64° (Hagerup); and one of the eastern 

 form was taken October 28, at San Jos6 del Cabo, Lower California 

 (Brewster) . 



Spring migration. — The following records include both the eastern 

 and western forms: The species arrives in the southern United 

 States in March; Tallahassee, Fla., March 25, 1901 (WiUiams); 

 Coosada, Ala., March 28, 1878 (Brown); Bay St. Louis, Miss., March 

 17, 1902 (Allison); New Orleans, La., average March 16, earliest 

 March 5, 1900 (Allison); Boerne, Tex., March 25, 1880 (Brown); 

 while some of the earliest records in California are at Los Angeles, 

 April 21, 1897 (Grinnell), and Gridley, April 23, 1891 (Belding). 

 Further progress northward is decidedly slow, as shown by the fol- 

 lowing dates of arrival: Raleigh, N. C, average April 24, earliest 

 April 4, 1889 (Brindey); near Asheville, N. C, average April 22, 

 earliest April 9, 1890 (Cairns); Washington, D. C, average April 28,

 earliest May 1, 1897 (Pierce); eastern Massachusetts, average May

 1887 (Willis); Pictou, Nova Scotia, May 7, 1894 (Hickman); Lake 

 Mistassini, Quebec, May 23, 1885 (Macoun); central Iowa, average 

 April 25, earliest April 10, 1899 (Savage) ; Chicago, 111., average April

 earliest April 23, 1903 (McAtee); Oberlin, Ohio, average April 29,
